However, care should be taken in analog line extension applications, to make sure that the flash-hook

event is allowed to be relayed over SIP or H.323. This can be achieved by disabling all local call

features in the fxs interface on context cs: no call-waiting, no additional-call-offering, no call-hold.

CTS10392

The internal timer configuration command is only able to execute commands that produce an immediate

result. Some commands that execute asynchronously cannot be executed by the timer. The following

commands (among others) cannot be executed by the timer:

 ping

 traceroute

 dns-lookup

 copy any kind of files from or to a TFTP server

 reload without the forced option

CTS10553

The command “no debug all” does not fully disable the ISDN debug logs. As soon as any other ISDN

debug monitor is enabled, all the ISDN monitors that were disabled by “no debug all” are re-enabled.

CTS10586

The codecs G.723 and G.729 cannot be used at the same time on all platforms, except on the

SmartNode 4960.

SmartNode 4960 Gigabit Ethernet does not properly work with Dell 2708 Gigabit Ethernet Switch. A

work-around is to configure 100Mbit.

CTS10730

Due to memory limitations it is not possible to download a software image to the SN4552 when two SIP

gateways are active.

CTS11114

On SN46xx units it can happen that there are more open phone calls requiring a DSP channel than

DSP channels are available. This leads to the situation where a phone connected on a bri port rings and

has no voice after the user picks it up. To limit the number of calls using DSP channels it is suggested

to create a limiter service where each call from and to a bri port has to pass. When the total number of

calls on the bri ports is limited to the number of DSP channels each call is going to have audio on

picking up.

CTS11214

SmartWare supports on Ethernet ports only the full functionality when the remote device does auto

negotiation for link speed and duplex mode. Even when there is a setting configured auto negotiation is

proceeded, but only with the configured capabilities. If connected switches do not auto negotiation there

can be limited speed or even no link.
